Embodiment
In order to describe structure of the present utility model, characteristics and effect in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
Extremely shown in Figure 5 as Fig. 1, the shutter assembly 10 of the camera that is provided for the utility model first preferred embodiment, it includes: a pedestal 20, one first magnet valve 30,2 first magnetic conductive parts 40, two blades 50, one second magnet valve 60,2 second magnetic conductive parts 70 and an aperture blades 80.
Each first magnetic conductive part 40 is located at the chassis 22 of pedestal 20 and is positioned at first magnet valve, 30 1 sides, corresponding respectively each first magnetic 34 of each first magnetic conductive part 40.Each first magnetic conductive part, 40 position is defined as a primary importance P1 and a second place P2 respectively, and first rocking handle 32 can displacement between primary importance P1 and second place P2.The type of each first magnetic conductive part 40 is for being selected from column, sheet, arc sheet and cylindric wherein a kind of.In the present embodiment, each first magnetic conductive part 40 is to be example with cylindric, and only for illustrating, conduct does not limit important document at this.
Each blade 50 has two perforation 52, the perforation 52 of blade 50 one of them be hubbed at pedestal 20 chassis 22 projection 25,26 one of them, one of them wears (as shown in Figure 4) for the protuberance 321 of first rocking handle 32 in another perforation 52 of blade 50, thus, each blade 50 connects first magnet valve 30 and is driven by first rocking handle 32.In the present embodiment, the quantity of each blade 50, only for illustrating, conduct does not limit important document at this.
Each second magnetic conductive part 70 is located at the chassis 22 of pedestal 20 and is positioned at second magnet valve, 60 1 sides, corresponding respectively each second magnetic 64 of each second magnetic conductive part 70.Each second magnetic conductive part, 70 position is defined as one the 3rd position P3 and one the 4th position P4 respectively, and second rocking handle 62 can displacement between the 3rd position P3 and the 4th position P4.The type of each second magnetic conductive part 70 is for being selected from column, sheet, arc sheet and cylindric wherein a kind of.In the present embodiment, each second magnetic conductive part 70 is to be example with cylindric, and only for illustrating, conduct does not limit important document at this.
As shown in Figure 6, through adopting said structure, when first coil groups 36 changes magnetic field, each first magnetic 34 is subjected to magnetic field induction, order about first rocking handle 32 from primary importance P1 toward second place P2 displacement, each blade 50 can make aperture become open state by closed condition, to reach the purpose of control aperture.
As shown in Figure 7, be the magnetic attraction curve map and the activation force profile figure of first magnet valve 30.Wherein, the magnetic attraction curve of first magnet valve 30 is S1, and first magnet valve, 30 activation force profile are S2.When first rocking handle 32 was positioned at primary importance P1, the rotational angle that defines first rocking handle 32 was 0 degree.When first rocking handle 32 was moved to second place P1, the rotational angle that defines first rocking handle 32 was 25 degree.
When first rocking handle 32 is positioned at primary importance P1 and since each first magnetic 34 one of them be positioned at first magnetic conductive part 40 of primary importance P1 via magnetic absorption, and then make first rocking handle 32 stably be positioned at primary importance P1.
When first rocking handle 32 relatively away from first magnetic conductive part 40 that is positioned at primary importance P1, because first magnetic conductive part 40 itself does not have magnetic, first magnetic 34 can weaken relatively, and the resistance of relative first rocking handle 32 is reduced, and then is beneficial to and makes first rocking handle 32 away from primary importance P1.
When close relatively first magnetic conductive part 40 that is positioned at second place P2 of first rocking handle 32, because first magnetic conductive part 40 is each first magnetic, 34 one of them generation sense magnetic relatively, and then produce a magnetic attraction relatively, the suction of relative first rocking handle 32 is strengthened relatively, and then be beneficial to first rocking handle 32 is quickened near second place P2.
When first rocking handle 32 is positioned at primary importance P2 and since each first magnetic 34 one of them be positioned at first magnetic conductive part 40 of primary importance P2 via magnetic absorption, and then make first rocking handle 32 stably be positioned at second place P2; At this moment, each blade 50 can make aperture be open state.
When to make first rocking handle 32 from second place P2 involution to primary importance P1, as long as change the magnetic field of first coil groups 36, its operating principle is not given unnecessary details in this appearance as hereinbefore.
In addition, removable each first magnetic conductive part 40, and first magnet valve 30 tested again, just can be used as control group.As shown in Figure 7, the magnetic attraction curve of first magnet valve 30 of control group is T1, and first magnet valve, 30 activation force profile are T2.In the comparison diagram curve just as can be known, each first magnetic conductive part 40 helps to improve the responsiveness of first rocking handle 32, has the advantage of certain raising responsiveness.
As shown in Figure 8, when second coil groups, 66 change magnetic fields, each second magnetic 64 is subjected to magnetic field induction, thereby orders about second rocking handle 62 from the 3rd position P3 toward the 4th position P4 displacement, the neutral density filter 84 of aperture blades 80 can cover aperture, and then the dim light effect is provided.Wherein, because first magnet valve 30 is identical with the structure and the operating principle of second magnet valve 60, do not give unnecessary details in this appearance.
Thus, the shutter assembly 10 of camera that the utility model provides passes through said structure, can provide a static confining force by the sense magnetic action of each first magnetic conductive part 40 and each second magnetic conductive part 70, so that the action of first rocking handle 32 and second rocking handle 62 puts in place really, and then the operating state of the shutter assembly 10 of stabilized camera.In other words, first rocking handle 32 and second rocking handle 62 can be kept steady state (SS) and can not produce and rock skew after putting in place, can't be stable at the shortcoming of fixed position state after the shutter assembly that further overcomes known camera puts in place, have the certain characteristic of action than the shutter assembly of known camera.
Moreover, simple and the integral body of the shutter assembly member of camera of the present utility model generally is flat, and it is than the shutter assembly of known camera, under the identical prerequisite in installing space, needed space when the utility model can reduce installing relatively has the less characteristic of volume.
The utility model only for illustrating, can not be used for limiting scope of patent protection of the present utility model by the constituent components that previous embodiment disclosed, and substituting or variation of other equivalent elements also should be contained by scope of patent protection of the present utility model.
